How do I know the real location? SFO seems irreasonable with that latency
How do I know the real location? SFO seems irreasonable with that latency
CThat IP exists in more then one location (anycast) so it's hard to assign a single location to it
SYes, Anycast it is!
CIn general, you can go to
/cdn-cgi/tracehttps://d1-a-ut.makemyparty.live/cdn-cgi/trace, and look at colo={airportcode}, and that airport code is the identifider of the location you hitCOf course, you can't do that with most looking glasses, so you just have to guess by ping time or if traceroute or reverse dns exposes something obvious. Sometimes you'll see one of the end IPs be an Internet Exchange making it pretty obvious
SAnd I would have to do this from within India if I want to really locate that colo (in this particular case)
SIs there a cloudflare utility like thatof Vultr that allows me to trace it locally to a region?
Cfor example:
Cif you google
38.10.0.47, you get a peering db result, it's CF's IP for them on Extreme IX in Bangalore, so it's most likely going to Cf's Banglore coloSgotcha!
Cshould probably go to #off-topic or #general-help since this isn't workers related
Aif i am using durable objects for rate limiting should i use an alarm to delete buckets that are inactive?
DIs there a way I can have my Worker "push" data back so that the client doesn't disconnect?
Dis there a 100,000 ms limit or something on a Worker?
J100s is the default timeline for Cloudflare http things
DI increased the proxy timeout to 6000s; I thought that would apply?
DIs there no easy way to increase that?
JHi all, I'm building an API. I need to find some data from a relatively large file (1~3 GB). The file is encrypted, so I also need a functional algorithm to decode the data from the file. What data storage solution should I choose? Thank you.
RIs there a max body size in Cloudflare Workers? I need to handle files (using FormData for example) up to 2GB

VHello, is it possible to modify HTML of react site using cloudflare workers with HTMLRewriter?
If my understanding is correct cloudflare workers modify HTTP responses.
But on react site there is not a new HTTP request when page is loaded because react works by changing DOM content.
Any help and explanations would be greatly appreciated!

HHTMLRewriter can only modify HTML that exists Server-Side. Generally, React uses a single div, that is then populated on the client side. So unless you can get React to do some of the work on the server, then no
DDwat, I thought more than 5 subrequest connections would just queue up?
HMaybe you are hitting this?
Dna, I am not doing anywhere near 1000 requests
HHow about 50?
Dnope. I'm doing:
5 subrequests to R2 through the bindings.
5 subrequests to the Cache API
2 subrequests to Backblaze B2
If I await between the R2 put's and the Cache API put's, the error goes away.

HMight be this?
If the system detects that a Worker is deadlocked on open connections — for example, if the Worker has pending connection attempts but has no in-progress reads or writes on the connections that it already has open — then the least-recently-used open connection will be canceled to unblock the Worker.Otherwise, not sure what it could be
If the Worker later attempts to use a canceled connection, an exception will be thrown. These exceptions should rarely occur in practice, though, since it is uncommon for a Worker to open a connection that it does not have an immediate use for.
DI wonder if there's an undocumented limit still for internal subrequests
HI don't think so? Pretty sure I've run 20+ concurrently before
Dwouldn't that be an exception, not a "Too many subrequests"?
Dto the cache api?
HI would assume not, but can't be sure just from the dash
HThe Cache API, DOs, KV. 20+ each
HI can try passing it up to see, but otherwise, might be worth a ticket
Dhuh, weird.
Dwith the same ReadableStream source?
Dfor context, what I'm doing, is shoving the same data into five R2 buckets in each region, and also pushing it into the Cache API (so I avoid a Class B completely in even more situations).
HNo, they were different. Just got a response though, so looks like what you were doing(awaiting them halfway through) is what you are supposed to do
Doh, why is that? I thought this would cause buffering and be bad.
Hcache.putR2Object, but that doesn't actually include the body. For the two requests to Backblaze, you can call response.body.cancel() to ensure they are closedDI mean buffering of the input 
HWell, they wouldn't be processed entirely in parallel anyway, since it would only be running half of them at once
HSo it would already be buffering it somewhere
Dhm, good point. I guess it'll probably be fine, since I only take in files <100MB
HOtherwise, you can put it to R2, then pull it back out into Cache. Might be convoluted, but 
Doh I was just optimizing so I never technically have to pull from R2 
TIs there a way to publish a JSON environment variable via the dashboard? Docs show how to do this in Wrangler but not the dash (https://developers.cloudflare.com/workers/configuration/environment-variables/)
Cloudflare Docs
Attach text strings and JSON values as environment variables to your Worker.
